Description
Technical field
This utility model relates to the Devolatilization device of a kind of silicone-based polymers, belongs to devolatilization equipment technical field.
Background technology
Compared with tradition rubber, organic silicon rubber has high-low temperature resistant, low compression set, processing type and the biocompatibility etc. of excellence, thus is widely used in chemical industry, machinery, automobile, electronics, medical treatment and articles for daily use.Additionally, the primary raw material of silicone rubber is not from petroleum-based energy, thus there is huge development prospect.Organic silicon rubber mainly includes dimethyl silicone rubber, methyl vinyl silicone rubber, fluorosioloxane rubber, phenyl siloxane rubber and copolymerization organic silicon rubber, and in organic silicon rubber production process, devolatilization is a requisite step.Directly influence the quality of goods owing to waving part, thus silica gel has the silica gel product of strict restriction, food stage and medical grade higher to the requirement waving part to waving part content in producing.Various silicone rubber to wave part different, part mainly waved by dimethyl silicone rubber is octamethylcy-clotetrasiloxane, and fluorosioloxane rubber is mainly tetramethyl four (trifluoro propyl) cyclotetrasiloxane, wave part boiling point at ambient pressure for two kinds and be respectively 175 DEG C and 325 DEG C, it is inferred that the devolatilization of fluorosioloxane rubber is more much more difficult than silicone rubber.
Conventional silicone rubber devolatilization equipment has devolatilization screw rod, vacuum kneader and devolatilization still etc., utilizes screw rod devolatilization efficiency high, but the shearing under high temperature easily causes the degraded of polymer；Vacuum kneader and devolatilization still belong to batch (-type) devolatilization, and production efficiency is low, power consumption height, and the high boiling point being difficult to remove fluorosioloxane rubber or copolymerization fluorosioloxane rubber waves part.
